LASTINGr-MACHINE.

Specification of Letters Patent. I Patented @4313. 26, 1915.

Application filed January 16, i914. Serial No. 812,475,

To all whom it may concern:

Be it known that I, JOHN W. RYBERG, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain Improvements in Lasting-Machines,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to shoe machines and particularly to a work rest,as for example a toe rest which supports the toe portion of the shoefrom beneath and, on a bed lasting machine, is usually so arranged thatit may be elevated to force the shoe into the heel band in the operationof jacking the shoe.

The toe rest of the commercial'machine is arranged to tip freely toaccommodate its upper face to the plane of the surface of the last withwhich it engages. This is necessary because modern lasts varyconsiderably in thickness at the two lateral sides. shoe engagingsurface of a pad of this construction, when used in lasting shoes inwhich the difference in thickness between the two lateral sides ispronounced, isv considerably inclined to the horizontal and hence thereis a tendency for the shoe to slide laterally along the inclined upperface of the rest, resulting in displacement of the shoe laterallyrelatively to the wipers which, when advanced, fail to Wipe in the upperevenly upon the two sides of the shoe. In some modern lasts the thickestportion of the forepart is on the outside of the toe and therefore thetendency is for the shoe to swing toward the outer or more curved sideof the toe during the lasting operation. It is consequently desirable toprovide means adjacent to or upon the toe rest which will serve toposition the shoe laterally relatively to the wipers before the shoe isjacked and which will also serve as a stop to hold the shoe fromslipping to one side when, in jacking the shoe, the face of the rest isbrought to bear upon the toe portion of the shoe in an inclinedposition. It is also desirable that means be provided for shifting thetoe rest with the stop in a lateral direction so that the shoe may beaccurately posi tioned relatively to the wipers.

When the shoe is unjacked there is a The tendency, before the pressureof the toe rest against the toe portion of the shoe has been released,for the toe rest to remain in position while the shoe moves bodilyrearwardly relatively to the toe rest. Moreover in lasting shoes havinghigh toes it is very hard for the high toe to pass over the toe rest asthe shoe moves rearwardly in the unjacking operation. In either case thetendency is for the toe to drag across the toe rest and objectionablerubbing and possible marring of the upper leather may result. This isthe case whether or not the toe rest is mounted for free movementlongitudi nally of the shoe, because during the application of pressureto the shoe by the toe rest free movement of the latter is impossible.

Modern lasts are so shaped that the lowest 1 part or region of the toeportion of the shoe extends diagonally across the toe in one directionfor a right shoe and in the opposite direction for a left shoe. It istherefore desirable that the toe pad shall have provision for adjustmentinto a position at an angle to the longitudinal median line of the shoeso as to bear alongthe lowest part of the toe portion of the last andhold the upper material against'the last at the portion where it has thegreatest tendency to bridge across from the instep to the toe. In thisconnection it is desirable that the toe rest have adjustmentlongitudinally of the shoe so that the pressure of the toe rest may bebrought to bear upon the lowest portion of the shoe longitudinally.

It is the object of the present invention to provide a toe rest whichwill possess the advantages and will obviate the disadvantages abovenoted, and as a feature of the invention means is provided forpositioning the shoe relatively to the toe rest before pressure isapplied through the toe rest to the shoe to jack the shoe. For thispurpose a stop member is provided upon the toe rest for usealternatively at either side of the shoe at the lateral end of the toepad which serves whenpositioned upon one side of the shoe to locate aleft shoe relatively to the wipers and when positioned upon the otherside of the shoe similarly to position a rightshoe relatively to thewipers. In the construction shown the toe rest is mounted for movementabout a center which lies substantially in the surface of the pad orcushsegmental portion which is mounted in a corresponding recess in amember carried upon the toe post. The adjustable stop member in theconstruction shown is mounted to be adjusted peripherally of thesegmental portion of the toe rest into positions such that either oneend or the other of the member may project above the face of the toe padin position to serve as a limiting stop for positioning the toe of theshoe laterally. Means is provided for holding the stop member inadjusted position and the member preferably has an intermediate positioninwhich neither end will project above the surface'of the toe rest.

To cooperate with the stop member in properly positioning the shoelaterally, means is provided for adjusting the toe rest laterally oftheshoe which preferably comprises ascrew and hand wheel. In use the stopmember is adjusted so as to engage the outer side of the toe and thescrew for laterally adjusting the toe rest is operated to bring the shoeaccurately into position relatively to the wipers.

A. toe rest is provided which will move with the shoe during theunjacking operation without relative movement of the engaging surfacesof the pad and shoe. To effect this a pad which may be substantiallycylindrical in shape is mounted upon the top of a toe rest and isconveniently formed by rolling a strip of leather or other yield in}; orresilient material upon a core, although the core is not at allnecessary. The pad is preferably mounted upon the toe rest so that itwill roll under the shoe as the shoe moves rearwardly during the unacking operation and this result may be effected by hinging the roll tothe rear face of the toe rest, as for example by fastening to the rearface of the toe rest the end of the ma- I terial of which the rollis'composed. This arrangement permits the toe pad to move rearwardlywith the shoe during the unjacking operation, but holds the pad firmlyagainst forward movement relatively to the rest.

As another feature of the invention the toe rest is arranged foradjustment about a vertical axis into positions of opposite inclinationto the longitudinal median line of the machine so as to bring the toepad into contact with the lowest part of the toe portion of the last. Toeffect this, the toe post which supports the toe rest and pad is mountedfor movement about its longitudinal axis, and means is provided forholding the post in various positions which are preferably predeterminedand may conveniently include a position in which the toe pad willextend'at right angles to the longitudinal median line of the shoe whenthe machine is to be used on straight lasts and to opposite 'positionsof inclination to that line when used respectively upon right and leftlasts. Means is also provided for adjusting the rest longitudinally tobring the pressure of the rest against the lowest portion longitudinallyas well as diagonally of the last.

As another feature of the invention, the

toe post is detachably connected to the toe head and may be detached andreversed in position so that the adjustment of the toe rest relativelyto the wipers may be greatly varied.

' These and other features of the invention, including certain novelconstructions and combinations of parts, will appear more fully from thefollowing detailed description when read in connection with theaccompanying drawings and from the appended claims. I

Figure 1 is a sectional view of a bed lasting machine showing a toe restembodying the invention in its relation to the other parts of themachine; Fig. 2 is a perspective view of the toe rest; and Fig. 3 is adetail view.

In the drawings, 2 indicates the vertically movable toe head of a bedlasting machine having the stem 3 arranged to slide up and down in theframe of the machine and carrying the wipers 4t which are advanced andclosed by the lever 6 to wipe in the upper about the toe portion of theshoe. At 8 is indicated a slide upon which rests a toe post 10 and whichis moved vertically to raise the toe rest in the operation of acking theshoe. To support the toe post 10 in a vertical position, a block 12 isprovided which has a groove 14 fitting a dovetail upon the upper portionof the slide 8. This construction permits the block 12 to be movedhorizontally on the slide 8. It is desirable that the block 12 be movedlongitudinally of the shoe with the toe head when the latter is adjustedfor length of shoes, but not when the latter is moved to advance orretract the wipers during the lasting operation on a jacked shoe. Toeffect this in the construction shown the connection 16 is providedwhich is secured at 18 to the toe head and comprises arms which haveinturned ends that rest in V-shaped recesses 20 formed in the oppositesides of the block 12. When the toe lasting head occupies its normaldepressed position the ends of the arms are located in the lower narrowportions of the recesses 20, and therefore when the toe lasting head isadjusted longitudinally of the machine by the usual hand wheel, Fig. 1,for the length of the shoe to be lasted the toe rest will be adjustedwith the head. When the toe lasting head is raised to the position shownin Fig. 1 for wiping the upper over the bottom of the last the ends ofthe arms are raised into the wider portions of the recesses 20, as shownin said Fig. 1, and then the toe last ing head can be advanced orretracted as may be required for the lasting operation the shoe. Theposition of the block 12 may also be reversed on the slide to vary theposition of the toe rest longitudinally of the shoe. The post 10 isprovided with the usual adjusting screw 22 by which the height of thetoe rest may be varied.

On the upper end of the post 10 a block 24 is mounted which has ahorizontal upper face. A block 26 has suitable dovetail or otherconnection with the block 24 to permit adjustment of the blocksrelatively to each other in the direction of the length of the shoe, andmeans is provided for holding the blocks 24, 26 in various predeterminedpositions of adjustment which may comprise a button 28 pivoted to theblock 26 and adapted to engage notches 30 to permit ad justment of theparts as described.

A box 32 is guided upon the block 26, preferably by suitable dovetailconnections, for movement laterally of the shoe, and means is providedcomprising a screw 3%. having a hand wheel 35 and threaded engagementWith the box 32. The screw is held from longitudinal movement in theblock 9:6 to hold the box 32 from lateral movement upon the block 26 andfurnishes a fine adjustment for said box in a transverse direction. Bythis adjustment the operator is enabled to adjust the toe rest which carrice the stop member laterally of the machine to locate the shoeaccurately with relation to the wipers.

Mounted in a suitable recess in the upper face of the box 32 is asegmental toe rest member 36 which is held in the box and is permitted alimited movement by a pin 38 secured to the member 36 and engaging acurved slot tO in the box 32. Preferably the curvature of the member 36is such that it moves about a center located substantially in the upperor shoe engaging face of a pad 4-2 resting on the upper face of themember 36. The pad -12 may comprise a strip of yielding or resilientmaterial, for example leather, rolled either upon itself or upon asuitable core and having the free end of the roll secured as at 46 tothe member 36. It is to be noted, of course, that a roll of any suitablematerial or construction may be employed without departing from theinven tion, it being essential only that the roll be so secured,preferably at the rear upper edge of the member 36, that the roll maymove With the shoe during its movement in the unjacking operation.

The upper face of the member 36 upon which the roll l2 rests may beprorided with suitable undercut grooves extending lengthwise of itssurface and transversely of the shoe to receive a facing of leather,rubber or other suitable material to enable the rest to be used withoutthe roll or pad 4%.

To enable the pad 4:2 to be positioned at an inclination to thelongitudinal median line of the forepart of the shoe so as to engage thelowest portion of a last having pronounced right and leftcharacteristics, that is, lasts in which the lowest portions of the topfaces extend across the foreparts of the lasts in directions oblique tothe longitudinal axes of the lasts, the rest is mounted for adjustmentinto predetermined positions about the longitudinal axis of the post 10,the post being held in the said positions of 'ad'ustment b a )in 50thereon which ma engage any one of a series of notches formed in theblock Adjustment of the rest is made by raising the post to free the pin50 from the notches and then rotating thepost into the desired positionof adjustment. lVhen released the pin 50 will engage the notch 52corresponding to the adjust-- ment and the post will be held fromrotation.

To provide means for positioning the toe portion of the shoe laterallywith respect to the toe head and wipers of the machine prior to thejacking of the shoe and to prevent the forepart of the shoe from slidinglaterally on the toe rest when, to bear evenly upon the toeportion, therest has assumed an inclined position, a member is provided whichiscurved on a radius substantially the same as that of the member 36 andis mounted in a groove in the box 32 beneath the men'iher 36. The stopmember 60 is therefore capable of movement about the periphery of thecurved lower face of the member 36 and may be positioned with one endopposite the corresponding end of the pad 42 to serve as a positioningstop for one side of a right shoe, or with. its opposite end adjacentthe other end of the pad 42 to serve as a positioning stop for a leftshoe. YVhen in an intermediate osition of adjustment the stop menr ber60 does not project above the pad 42 at either end and is then, ofcourse, in an inoperative position. The member 60 is held in its variouspositions of adjustment by a spring detent 62 which is adapted to engageany one ofa series of holes (ii formed in the member (30.
